Description

Everyone thinks they know bash if they can type a few commands. Hey, you don’t know bash! Carl Albing leads a fast-paced tour of some of the newest features and most useful idioms in bash—the shell everyone needs to know—for better scripting, faster sysadmin-ing, and everyday work in open source development.

Carl begins by outlining eight powerful bash features that make bash more than just a simple scripting language (four kinds of “for” loops, many kinds of “if” statements, shell functions and redirections for robust scripting, and more). He then shares 10 things you probably don’t know about bash that will make your virtual life easier, covering shortcuts and idioms that put more power at your fingertips. Carl concludes with a review of the bash 4.x features that have beefed up bash and made it even more powerful and more useful.
